Jjdancer replied to the thread ESXi → Proxmox migration: Host CPU vs x86-64-v4-AES performance & 10 Gbit VirtIO speeds.Per https://www.proxmox.com/en/services/training-courses/videos/proxmox-virtual-environment/whats-new-in-proxmox-ve-9-1 for Windows Server 2025 VMs, you'll want to enable the nested-virt flag under Extra CPU Flags options.

Jjdancer replied to the thread ddr4 intel optane.Since Proxmox is Debian with an Ubuntu LTS kernel, it should work. If it was me, I would just go straight to flash storage and skip it. I do, however use the Intel Optane P1600X as a ZFS RAID-0 OS drive for Proxmox without issues.
-
Jjdancer replied to the thread VMware user here.If you plan on using shared storage, your officially Proxmox supported options are Ceph & ZFS (they do NOT work with RAID controllers like the Dell PERC). Both require an IT/HBA-mode controller. I use a Dell HBA330 in production with no issues.

Jjdancer replied to the thread Dedicated Migration Network vs. High Speed Storage Network: Do I need two separate VLANs when Clustering?.Technically, you do not if this is a home lab, which I am guessing it is. Now, it is considered best production practice to separate the various network into their own VLANs especially with Corosync with it's own isolated network switches...

Jjdancer replied to the thread H330 sas controller failed after upgrading to Kernel 6.17.2-2-pve.Better off with a Dell HBA330. It's a LSI 3008 IT-mode controller chip anyhow. Just make sure to update the firmware to lastest version at dell.com/support

Jjdancer replied to the thread The SSD search continues ....As was mentioned, getting new drive is "nice" but not really required. With a reputable enterprise flash drive, getting it used is fine. I have used 5-year-old Intel enterprise SSDs and they still show 100% life. At home, I use Intel Optane...

Jjdancer replied to the thread The SSD search continues ....This thread at https://forums.servethehome.com/index.php?threads/enterprise-ssd-small-deals.48343 has a list of enterprise SSDs for sale. Another option is getting a server that supports U.2/U.3 flash drives. They can be surprisingly cheaper...

Jjdancer replied to the thread H740p mini and SAS Intel SSD PX05SMB040.I compile this utility to format SAS drives to 512-bytes or do a low-level format https://github.com/ahouston/setblocksize You'll need to install the sg3_utils package. While doing that, might as install sdparm package and enable the write...

Jjdancer replied to the thread H740p mini and SAS Intel SSD PX05SMB040.Don't forgot to flash the HBA330 to the latest firmware from dell.com/support

Jjdancer replied to the thread H740p mini and SAS Intel SSD PX05SMB040.As I mentioned before, so much drama with PERC controllers in HBA-mode. Just swap them out for a Dell HBA330 true IT-mode storage controller. Your future self will thank you. They are cheap to get.

Jjdancer replied to the thread [Help] Dell R740 + Broadcom BCM5720 NDC - Ports Active (Lights On) but Not Detected by Proxmox.I use Dell Intel X550 rNDC in production without issues. Both the 2x1GbE-2x10GbE and 4x10GbE versions. The 10GbE uses the ixgbe driver and the 1GbE uses the igb driver. Use 'dmesg -t' to confirm. Obviously flash the rNDC to the latest firmware...

Jjdancer replied to the thread H330 sas controller failed after upgrading to Kernel 6.17.2-2-pve.It's these one-off situations with the megaraid_sas driver and just installing a Dell HBA330 using the much simpler mpt3sas driver will avoid all this drama. LOL. In addition, the Dell HBA330 is very cheap to get.

Jjdancer replied to the thread Esxi migration to proxmox.While it's true 3-nodes is the minimum for a Ceph cluster, you can only lose 1 node before losing quorum. You'll really want 5-nodes. Ceph is a scale-out solution. More nodes/OSDs = more IOPS. Can lose 2 nodes and still have quorum. While...
-
Jjdancer replied to the thread Storage for production cluster.You need to really confirm that write cache enable is turned on via 'dmesg -t' output on each drive. If the write/read cache is disabled, it really kills the IOPS. While technically 3-nodes is indeed the bare minimum for Ceph, I don't consider...

Jjdancer replied to the thread Proxmox VE 9.1 Installation on Dell Poweredge R630.On 13G Dells PVE hosts running 6.17.2-2 kernel. I have UEFI, Secure Boot, X2APIC, I/OAT DMA enabled. I do NOT have SR-IOV enabled.
-
Jjdancer replied to the thread Storage for production cluster.Been migrating 13G Dells VMware vSphere clusters over to Proxmox Ceph using SAS drives and 10GbE networking on isolated switches. Ceph is scale out solution, so more nodes = more IOPS. Not hurting for IOPS on 5-, 7-, 9-, 11-node clusters. Just...

Jjdancer replied to the thread Shared Storage across 10GB Fiber for a ProxMox Cluster?.Plenty of past posts on NOT running Promox on SD cards. It will cause instability and crashes.

Jjdancer replied to the thread Opt-in Linux 6.17 Kernel for Proxmox VE 9 available on test & no-subscription.Actually had to pin 6.14.11-4 kernel on PBS instances. 6.17.2-1 was giving intermittent issues on BOSS-S1.

Jjdancer replied to the thread Shared Storage across 10GB Fiber for a ProxMox Cluster?.Disclaimer: I do NOT use ZFS shared storage in production. I use Ceph for shared storage. I do use ZFS on standalone servers. I ZFS RAID-1 to mirror Proxmox on small 76GB SAS drives. With that being said, your best bet is ZFS over iSCSI per...
